Hi, i need a solution/plugin that can change the links of all my posts from my blog-overview to the orginalfile (jpg/png) of the featured image.

Normaly its like:

BlogPost (with Featured Image) > click > BlogPost with Content loads.

I'm looking for a way that makes it do this:
BlogPost (with Featured Image) > click > Orginal Featured Image JPG-URL loads.

I want that all my Posts just direct link to the orginal bigsize featured image url.
Would be very kind if someone help me out with this (i hope small problem), ts all about WordPress :)
